In this embodiment, the shoe light device is mainly composed of a bottom control box 05 (which is filled with resin glue to meet waterproof and impact-resisting requirements), an electronic connecting wire 06 SMT (surface mounted technology) or DIP (double in-line package), LED lights 10 and an external control button 08;

The bottom control box 05 is composed of an integrated chip (IC) 01 for controlling the LED lights, one CR power supply battery 03 or two CR power supply batteries 03 connected in series, a motion sensor 04 or a motion sensor 04S (wherein the motion sensor 04S is of a surface-mounted type), and a first circuit board 02;

The bottom control box 05 welded to one terminal of the electronic connecting wire 06 through a pad on the first circuit board 02, and the other terminal of the electronic connecting wire 06 is electrically connected to the external LED lights to drive and control the LED lights 10.

In this embodiment, the motion sensor is of the following two different structures:

Referring to FIG. 5 and FIG. 6 , the motion sensor of Structure 1: the motion sensor 04 is composed of a spindle 041, a spring 042, silicone 043 and a shell 044, wherein the spindle penetrates through the center of the spring to be fixed, together with the spring, to the center of the shell 044 through the silicone 043.

As shown in FIG. 7 and FIG. 8 , the motion sensor of Structure 2: the motion sensor 04S is packaged through the surface-mounted technology and is composed of a spring 042S, a metal shell 044S and a spring fastener 043S, wherein the metal shell 044S and the spring 042S are welded and electrically connected to a pad of a main control panel of the integrated chip (IC).

The LED lights 10 are mounted on the second circuit board 09 and are electrically connected to the bottom control box 05 through the pad on the second circuit board 09 by means of the electronic connecting wire 06.

The positive metal contact 083 and the negative metal contact 084 are electrically connected to the base plate 07 through welding.

The integrated chip (IC) 01 is composed of an 8-bit single-chip microcomputer module and is additionally provided with a voltage monitoring module and a voltage control module on the basis of basic module circuits, and other modules are common structural modules formed by single-chip microcomputers.

The power supply battery 03 is composed of two CR batteries which are connected in series (the initial voltage of the CR batteries is 3.4V, and the voltage of the two CR batteries after series connection is 6.8V). Or, the power supply battery is composed of only one CR battery. Due to the fact that the voltage control module is additionally arranged in the integrated chip (IC), the input voltage of the integrated chip (IC) can reach 2-8V.

In this embodiment, the bottom control box is mounted on a heel of a shoe outsole 11, and the LED lights 10 are inlaid in the outer side of the outsole. The electronic connecting wire 06 is mounted in a mounting groove reserved in the bottom of the shoe. The control button is mounted at any position reserved according to the design and is electrically connected to the bottom control box 05 through the electronic connecting wire 06. Similarly, the solution can also be applied to garments and suitcases and can be installed and used just like it is installed and used on shoes.

The control button 08 mainly has three functions and is operated specifically as follows:

- First, overall control of on-off of the device: specifically, the control button 08 is long pressed for 0.5 s to enable this function;
- Second, control and turn-off of the brightness: specifically, in the on state, the control button 08 is long pressed for 0.5 s to gradually decrease the brightness of the LED lights from the original 100% by a gradient of 10%, and the LED lights are turned off when the brightness is decreased to 30%; that is, under the condition where the LED lights are on, the brightness of the LED lights starts to attenuate from 100% after the control button 08 is long pressed by 0.5 s. The brightness is decreased by 10% every 0.5 s, the LED lights are turned off 3.5 s later, and the brightness can be decreased to 50% by pressing the control button 08 for 2.5 s.

It should be noted that before entering into this operating mode, the LED light (L1) works and displays the corresponding brightness, and the other LED lights (L2-L6) do not work.

The control button 08 also has a flashing sequence switch function; specifically, under the condition where the LED lights are on, the flashing mode is switched every time the control button is pressed. (Briefly, the flashing mode is switched once every moment the control button is pressed, and the specific modes are implemented by sequences A-H.)

Operating principle of the control button: when the contact of the control button 08 is pressed, the arc metal shrapnel 082 in the control button deforms to 25 realize electrical connection of the positive metal contact 083 and the negative metal contact 084, and the potential of an input terminal of the integrated chip (IC) 01 is pulled to a low voltage from a high level. At this moment, a counter in the single-chip microcomputer works and the whole device is started 0.5 s later. In a standby state, the contact is short touched to switch the flashing mode, and this operating principle is the same as the starting principle, except that the recorded time is decreased to 50 milliseconds from 0.5 second. The brightness control and turn-off function is also the same as the starting principle.

The operating principle of the shoe light device capable of flashing in different modes of the invention is as follows:

Under the condition where the device is in a standby state, when the shoe moves (namely, a wearer moves), a resilience force will be generated at the moment the bottom of the shoe touches the ground under the effect of the gravity of the shoe and the acceleration of the wearer; this resilience force is transmitted to the spring 042 of the motion sensor 04 through the bottom of the shoe and the bottom control box 05, at this moment, the spring 042 in the motion sensor 04 vibrates vertically under the effect of the external force, and when the amplitude of vibration exceeds the radius of the spring, the spring 042 intermittently contacts with the spindle 041. As shown in FIG. 5 and FIG. 6 , at the moment the spring 042 knocks and contacts with the spindle 041 in the spring, the motion sensor 04 sends a series of pulse signals to a tenth input port of the IC 01 because the spindle 041 is connected to the negative pole of the power supply battery 03 (or, as shown in FIG. 7 and FIG. 8 , this resilience force is transmitted to a spring operating end 042SB of the spring 042S through the bottom of the shoe and the bottom control box 05, at this moment, the spring operating end 042SB vertically vibrates under the effect of the external force, and when the spring operating end 042SB vibrates to a certain height and touches the metal shell 044S, the spring 042S intermittently contacts with the metal shell 044S; at the moment the spring operating end 042SB knocks and contacts with the metal shell 044S, the motion sensor 04S sends a series of pulse signals to the tenth input port of the IC 01 because the metal shell 044S is connected to the negative pole of the power supply battery 03, wherein a spring welding end 042SA is to be welded and electrically connected to a pad of a main control panel of the IC).

As shown in FIG. 10 , the IC receives and counts the pulse signals; when the duration of reception of the pulse signals reaches 10 milliseconds, the reception of the pulse signals is stopped, and the device is started; at this moment, all the modules in the IC are switched to an operating mode from a standby dormant mode, and the LED lights are driven to emit light in a constant-sequence output mode. (The specific operating sequences A-H are explained below.) Wherein, as shown in FIG. 11 , the operating mode by sequence A is as follows:

- 0-40 MS: the LED light L1 works; 40-80 MS: all the LED lights are turned off;
- 80-120 MS: the LED light L2 works; 120-160 MS: all the LED lights are off;

- 320-360 MS: the LED light L5 works; 360-400 MS: all the LED lights are off; 400-440 MS: the LED light L4 works.

This process is reversely repeated four times at this frequency (that is, first time: L1-L5; second time: L5-L1; third time: L1-L5; and fourth time: L5-L1) to form a complete work cycle which lasts for 1440 MS.

Referring to FIG. 19 , Embodiment 2 of the invention is as follows:

- The invention further provides a driving method of the shoe light device capable of flashing in different modes. The driving method comprises the following steps:
- When the motion sensor recognizes a resilience force generated at the moment the bottom of the shoe touches the ground, a series of pulse signals is sent to the integrated chip;
- The integrated chip receives and counts the pulse signals, and the time at this moment is recorded to obtain the duration of reception of the pulse signals; and
- The integrated chip determines whether or not the duration of reception of the pulse signals reaches a preset threshold; if so, the integrated chip controls the light-emitting device to emit light in a preset constant-sequence output mode.

Wherein, the preset threshold is 10 milliseconds.

Furthermore, the driving method further comprises the following steps:

To sum up, according to the shoe light device capable of flashing in different modes and the driving method thereof, the motion sensor, the integrated chip and the light-emitting device are integrated on the shoe, and the motion sensor and the light-emitting device are electrically connected to the integrated chip; and the integrated chip is configured to control the light-emitting device to emit light in a preset constant-sequence output mode when the duration of reception of pulse signals generated by the motion sensor reaches a preset threshold, so that trigger control over the light-emitting device is realized. The shoe light device capable of flashing in different modes of the invention has the following advantages: the integrity of elements is high, the structure and the production process are simple, and the light-emitting device has various integrated cyclic output modes for flashing; the elements of a control circuit of the device are highly integrated, only one main control IC is needed, no peripheral electronic devices are needed, the structure is simple, the production process is simple, and various integrated cyclic output modes for flashing (including quick flashing, slow flashing and flashing with variable brightness) are realized, the display brightness can be controlled (through the external control button; the device can be switched to different flashing modes; when the device is not needed, the LED lights can be turned off; the brightness of the LED lights can be controlled at night), the standby power consumption is ultra-low (less than 0.2UA), the output power is high (the output power of a single output port can reach 100MA), and the input voltage is high (the input voltage reaches 3-8V). Because the main control IC is highly integrated and is additionally provided with a corresponding power management module, the standby power consumption of the main control IC under an input voltage of 8V is less than 0.2UA, and the defects of common main control ICs on the present market that the maximum input voltage is 5V, the standby power consumption is 3-5UA, and a series of auxiliary devices such as capacitors and diodes need to be additionally disposed at the power input terminal are overcome. Two CR batteries can be connected in series to supply power to the IC to meet the requirement for a high input voltage. However, if the voltage of an existing common control IC exceeds 6V, the IC will be damaged.
